BEST Lubricants For Door Locks

9 Best Lubricants For Door Locks In 2022 (Tested)

There are many parts that make up a door lock, and they all need to work together quietly and easily for it to work right. If they can’t move easily, they might be hard to use, which will annoy you and the person coming or going from your home.

With door lock lubricant, rust doesn’t build up on the surface of your locks, which usually happens when water gets inside and forms rust layers over time. If there aren’t any other problems, this could make it hard to open or close the door or lock or unlock it. When picking a lube for door locks, these are some of the most important things to think about:

Temperature: You should make sure that the lube you choose is safe to use in places with high temperatures. An oil-based lube can break down and stop working well at high temperatures.

Water resistance: An important quality of a good lube is that it can still work after being wet. This is important because a lot of people keep their bikes outside, where it could rain or snow.

Viscosity: The viscosity of lubricants is very different; some are very thin and others are very thick. This is important because it determines how long it takes for each product to get into an area and start working properly. If there is a problem with locks or chains sticking, using a thicker product might help solve the problem faster than using a thinner product. This is because thicker lubricants take longer to get into an area.

Straw Construction: One feature that makes it easy to put the oil on the latch is a straw construction. To use the straw, all you have to do is put it into the slot and spray lubricant all around it. These steps will make sure that the lube covers all parts of the keyhole, both the inside and the outside.

What to Look for When Buying Lubricant for Door Locks

Today, you can buy a lot of different kinds of oils. There are, however, some that are better. Before you buy the best grease for door locks, you should think about a few things.

Things You Should Look for in Door Lock Lubricant

1. Waterproof

The best lubricant for door locks should be waterproof. This means that even if it rains heavily or if there is heavy snowfall, your car will still be safe from all types of weather conditions because of this type of lubricant.

2. Non-Toxic

 The lubricant should not be toxic at all as this can cause side effects such as poisoning or even death when used by children who play with them unknowingly or by pets who lick them up as food sources which is common in many homes today where there are pet dogs and cats running around freely without supervision all day long. Therefore, you need to make sure that your chosen door lock lube is non-toxic and safe for everyone including children who might find their way into it accidentally while playing around indoors or outdoors.

3. Corrosion Protection

If you are using a lubricant on your car door locks, it should offer corrosion protection to prevent rusting of the lock and its components. This is especially true for vehicles that are parked outside in the elements for long periods of time.

4. Ease of Application

Lubricants can be applied manually or with special tools depending on the type of lock being treated and its location. For example, if you need to apply grease to a lock that is installed beneath a car seat, you will need an applicator tool to do so effectively. Similarly, if you are applying grease to an inside door handle, it may require some elbow grease because it is not as easy to access as other parts of your vehicle’s interior such as undercarriage parts or even exterior surfaces like doors and hoods which are typically easier to reach due to accessibility issues.


We have listed a detailed buying guides for how to choose the best lubricant for your door locks. Next you can choose whatever suits your door lock and circumstances.
